Phase 2 Geo-Environmental Site Investigation – Beachy Road, London


Construction of a mixed use five storey development, comprising both residential and commercial areas, including a basement


As part of the London 2012 Olympics, the London Legacy Development Corporation (LLDC) was formed to use the creation of the Queen Elizabeth Olympic Park to “develop a dynamic new heart for east London, creating opportunities for local people and driving innovation and growth in London and the UK.”

As part of the legacy of the Olympic Games, the area surrounding the Olympic Park is being transformed, with Fish Island and Hackney Wick at the forefront of the redevelopment. The site at Beachy Road, situated on Fish Island, is proposed to be redeveloped into a mixed use five storey development, comprising both residential and commercial areas.

Working alongside Falconet Properties, the LLDC, and ARUP acting as an intermediary environmental consultant for the LLDC, a proposed scope of works was agreed and included the production of Phase 1 Geo-Environmental Site Assessment followed by a Phase 2 Intrusive Ground Investigation.

The Phase 1 Geo-Environmental Site Assessment allowed REC to propose the most suitable site investigation, targeting any contaminants of concern related to the previous site uses, and nearby works such as an Abattoir directly adjacent to the site.

REC was commissioned by Falconet Properties to undertake the detailed Ground Investigation and Assessment at the site. In order to accurately establish the deeper geology at the site into which the piled foundations are to sit, REC’s office in South Croydon has drilled two boreholes to 25 metres using a cable percussive method, which can cope with man-made obstructions in the made ground. REC utilised two ‘strings’ of drilling casing (200mm and 150mm) in order to ensure that the target depth of each borehole was reached. REC also drilled seven shallow window sample boreholes to 5 metres to gain an understanding of the shallow ground conditions, with respect to contamination and waste classification, given a basement is proposed to cover the footprint of the site. Foundations of the surrounding structures were also inspected in four trial pits, and the mechanical strength of the shallower soils was determined by excavating two shallow trial pits and conducting bearing pressure tests.


Having completed the ground investigation, REC is providing Falconet Properties with a comprehensive ground investigation report that will be used to inform prospective contractors of the ground conditions and enable them to accurately design and cost the necessary foundations, as well as inform the client of further remedial works required at the site. This should remove the need for contingency sums and provide Falconet with a more cost-effective price from its contractors, saving them money in the long run.
